Jackdaws are scavenger birds, related to ravens and crows. They are fond of pumpkins, and are the greatest enemy of Wogglebugs.
Hundreds of Jackdaws live in a nest on the side of a mountain in a country to the south of the Land of Oz. Their nest was filled with many valuable baubles they had collected, from necklaces and rings to cash money. (The Marvelous Land of Oz)
